Push from github to heroku without downloading repo

You can’t push straight from Github to Heroku.

You’re going to have to use the third host to coordinate the push. This could be fired from a Github post-receive hook.

To sync straight across use something like:

git remote add github git@github.com:user/repo.git
git remote add heroku git@heroku.com:app.git

git push heroku refs/remotes/github/master:refs/heads/master
